What this workflow does
This AI workflow has 34 nodes and runs on a schedule (every day). Along the way it connects OpenAI Chat Model and Google Sheets.
How it runs
Trigger: On a schedule (every day).
- AI Agent: runs an AI agent, with model: LLM: Generate Raw Idea (GPT-4.1); 1 tool (Tool: Inject Creative Perspective (Idea)); output parser: Parse AI Output (Idea, Environment, Sound)
- Save Idea & Metadata to Google Sheets (Google Sheets): uses Google Sheets
- AI Agent: runs an AI agent, with model: LLM: Draft Video Prompt Details (GPT-4.1); 1 tool (Tool: Refine and Validate Prompts); output parser: Parse Structured Video Prompt Output
- Parse Scene Prompts into Individual Items (Code): runs custom JavaScript code
- Generate Video Clips (Wavespeed AI) (HTTP Request): calls an HTTP API
- Check if Video Generation Complete (If): checks a condition and branches into true / false
- Build Video Status Check URL (Edit Fields (Set)): sets or maps fields
- Wait: pauses before continuing
- Fetch Generated Video from Fal.ai Queue (Code): runs custom JavaScript code
- Poll Video Generation Status (HTTP Request): calls an HTTP API
…plus 17 more steps. See the full node list below.
